The PT Application includes the following question:
Have you ever been convicted, placed on community supervision whether or not adjudicated guilty, sentenced to serve jail or prison time or granted pre-trial diversion, or plead guilty, no contest or nolo contendere to any crime in any state, territory or country, or received a court order whether or not a sentence was imposed, including any pending criminal charges or unresolved arrests whether or not on appeal (excluding minor Class C traffic violations)? This includes expunged offenses and deferred adjudications with or without a finding of guilt. DUIs, DWIs and PIs must be reported.
This means you must report any felony or misdemeanor conviction when you apply. Normally, a misdemeanor would not prevent you from being licensed, but a felony conviction, especially in a health care field could disqualify you.
I would suggest you locate a local attorney who specializes in professional license issues (someone who has represented people before the PT licensing body is best, but someone who handles attorney and/or doctor licensing cases might be worth a phone call).
